Corrigendum

We regret that the acknowledgements in the review ‘White structure flaking (WSF) in wind turbine gearbox bearings: effect of ‘butterflies’ and white etching cracks (WECs)’ by M.-H. Evans, published in the January 2012 issue of MST (28, (1), 3–22), http://dx.doi.org/10.1179/026708311X13135950699254, were incomplete. The acknowledgements section should have read:

The support and informative discussions with sponsors, Dr C. Højerslev, Mr M. Lewis, Mr G. Plint, Dr B. G. Mellor, Professor R. Wood and Dr L. Wang are greatly appreciated, as is the FIB work conducted by Dr J. C. Walker at the Southampton Nano-Fabrication Centre (SNC).

In addition, the copyright to Fig. 7 is held by M.-H. Evans and J. C. Walker.

The online version of the paper has been amended to reflect these changes.
